Devices made of readily available oxide and carbon-based materials can produce clean hydrogen from water over weeks — according to new research.

The findings, co-led by Dr Virgil Andrei, a Research Fellow at St John’s College, University of Cambridge, with academics at Imperial College London, could help overcome one of the key issues in solar fuel production, where current earth-abundant light-absorbing materials are limited through either their performance or stability.
